Reformer Technology

This technology produces hydrogen from liquids, often alcohol, which can then be used in a fuel cell to produce electricity. TPG has been active in this field since the 1960’s. 

TPG have developed a commercial prototype packed bed methanol reformer, and a low temperature carbon monoxide selective oxidation system.

Our current expertise on fuel processors for Proton Exchange Membrane Fuel Cell systems started in 1990 with the development of a 10kW methanol-fuelled power system demonstrator. 

Storage

With the increasing trend to use hydrogen as a clean fuel, methods of storing and transporting a very light gas have been explored. The 3 main methods currently adopted:-

  • Road vehicles use compressed hydrogen at 350 or 700 bar stored in crash proof containers.
  • Adsorb it onto metal hydrides at low pressures and warm it to release it again – this can increase the packing densities by roughly 500 times. This method is sometimes used on submarines.
  • A greater reduction in storage volume is achieved by storing hydrogen as alcohol - methanol or ethanol. The alcohol is then reformed into hydrogen and carbon dioxide using a steam reformer.  A few submarines will be using this method hence TPG's focus on this area.

 

Development Projects

TPG has been involved with:

  • European Union  JOULE projects - Methanol Reformer with Catalytic Oxidation MERCATOX , Carbon Monoxide Clean Up / Hydrogen Separation, COCLUP/HYSEP
  • UK Department of Trade and Industry projects - gasoline/diesel reforming, methanol reformer life tests, methanol reformer modelling
  • UK Ministry of Defence projects - marine diesel, kerosene.
